  1. 1. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering

    Författare :Oskar Berntsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; Photoreceptor; Time-resolved X-ray solution scattering; Protein dynamics; Phytochrome; Light-oxygen-voltage; Cryptochrome;

    Sammanfattning : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. LÄS MER

  3. 2. Light-dependent magnetoreception in zebra finches : - from behaviour to receptor

    Författare :Atticus Pinzon Rodriguez; Funktionell zoologi; []
    Nyckelord :magnetoreception; radical-pair process; magnetic compass; orientation; cryptochrome; Taeniopygia guttata;

    Sammanfattning : It is well known that animals can use a wide variety of information sources to help them orient and navigate asthey move over short or long distances. Birds can rely on information from the sun, the skylight polarizationpattern, the stars, landmarks and the Earth’s magnetic field for orientation and navigation. LÄS MER

  4. 3. Regulation of chloroplast development during the greening process

    Författare :Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

    Sammanfattning : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. LÄS MER

  5. 4. Demography and Polyploidy in Capsella

    Författare :Kate St.Onge; Anna Palmé; Martin Lascoux; Ulf Lagercrantz; Richard Abbott; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; Mating system; Brassicaceae; flowering time; genetic diversity; Evolution; Biology; Biologi;

    Sammanfattning : Studies of demography and population structure give insight into important evolutionary processes such as speciation and diversification. In the present work I perform such studies in the genus Capsella, which has three species: C. grandiflora, an outcrossing diploid, C. rubella a selfing diploid, and C. LÄS MER

  7. 5. Deciphering the role of genetics and circadian rhythm in cluster headache

    Författare :Carmen Fourier; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cluster headache (CH) is a complex neurovascular disorder with a distinct circadian attack pattern. Although many aspects of the disease’s pathophysiology remain to be elucidated, it is likely caused by a combination of different genetic and environmental risk factors. LÄS MER
